WILLIAM O. LINCOLN, OF BRIDGEPOBT, CONNECTICUT, ASSIGNOB TO SAMUEL W.LAMBETH, OF PHILADELPHIA, PENNSYLVANIA.

FLY-FAN.

SPECIFICATION forming part of Letters Patent No. 228,466, dated .Tune 8,1880.

Application Elea Maren eo, Iseo. (No model.)

To all whom t may concern Be it known that I, WILLIAM O. LINCOLN, acitizen of the United States, residing at Bridgeport, in the county ofFairlield, State of Connecticut, have invented a new and usefulImprovement in Fly-Fans, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which- Figure l isa side elevation ofthe portion of a {Iy-fan embodying my invention. Fig.2 is a vertical section of aportion thereof. Fig. 3 is a horizontalsection in line a: a2, Fig. 2.

Similar letters of reference indicate correspondin g parts in theseveral figures.

My invention relates to an improvement in fans which have arms connectedto a staff, the rotation whereof is occasioned by a train of gearing,after the manner of clock-work, the motion of the blades which areattached tov said arms serving' to frighten flies and other insects.

The invention consists in supporting the collar to which the fan-armsare hinged at any desired or adjusted height ou the rotary staff bymeans of friction-springs, which are simple in construction and reliablein operation, and' may be entirely concealed within the collar.

Referring to the drawings, Arepresents the staff or shaft, rising from'astand or base, B, containing a mechanical power, such as clockwork, forrotating said staff, as is well known in the class of fly-fans.

C represents a collar, to which the arms D of the fan-blades are hinged,and which is iitted loosely on the staff A, so asto be raised andlowered relatively to theI height that it is desired to set the blades.

. Secured to the inner wall of one end of the collar are springs orspring-plates E, which converge so that their disconnected ends,preferably semi-cylindrical, bear at opposite places against the staff,and thus create friction for holding` the collar on the staff.

It will be seen that thecollar may be readily raised or lowered, inorder to adjust the height ofthe fanblade, simply by moving or shiftingit in the proper direction, and when it is set the springs bite theshaft, and thus hold the collar and parts without screws or otherfastenings. Vhen the collar is in the form of a chamber the springs arefurthermore inclosed thereby, and thus concealed and renderedinaccessible.

The friction of the springs is sufficient to cause the rotation of thecollar with the staff when the latter is a plain rod 5 butif the staffis corrugated the upper and lower walls of the collar are scalloped toaccord and engage with the corrugations of the sta-ff, without, however,interfering With the vertical adjustment of the collar. 1

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is The fan-supporting collar, in combinationwith friction-spri n gs secured to said collar, and adapted to bearagainst the rotary shaft passed through the collar, substantially as andfor the purpose set forth.

VILLIAM O. LINCOLN.
